Will People Be Able To Regrow Organs?
Will humans be able to grow replacement organs? LyGenesis aims to prove it can be done.
LyGenesis is a biomedical company hoping to deliver a technology that will allow patients to grow functioning organs. If successful the company’s cell therapies will disrupt organ transplantation allowing patients to grow their own. Instead of surgery, a person will do what some amphibians and reptiles do today when they lose a limb or tail.
The company is using the inherent nature of lymph nodes and their evolutionary function, turning them into rapid bioreactors. Our lymph nodes already do this when they produce infection-fighting T-cells. But LyGenesis’ therapies turn donated organ cells into biofactories that can become a source for producing viable organs in multiple patients. The only minimally invasive procedure involved is the engrafting of the cells into a patient’s lymph nodes to begin the process of organ development.
IIT Madras collaborates with NASA JPL to study microbes aboard ISS
The Indian Institute of Technology (IIT) Madras has announced a collaborative study with the Jet Propulsion Laboratory (JPL), the research hub of central US space agency National Aeronautics and Space Administration (NASA), to study the impact of microorganisms aboard the International Space Station. Observations from the research project will help create medical solutions to aid astronauts in long term human missions in space.
Explaining the observations, Karthik Raman, assistant professor at the department of biotechnology, IIT Madras, said that the collection of microbes, which includes a variety of bacteria and fungi, have occurred over time due to the astronauts that have been aboard the ISS over the past decades.
“Even though the ISS is a highly sterile environment, these microbes can play a big role in the way human presence in a space environment works — which our research work sought to highlight,” Raman said.
Study: Cancer-causing gas leaking from CA stoves, pipes
Gas stoves in California homes are leaking cancer-causing benzene, researchers found in a new study published on Thursday, though they say more research is needed to understand how many homes have leaks.
In the study, published in Environmental Science and Technology on Thursday, researchers also estimated that over 4 tons of benzene per year are being leaked into the atmosphere from outdoor pipes that deliver the gas to buildings around California — the equivalent to the benzene emissions from nearly 60,000 vehicles. And those emissions are unaccounted for by the state.
The researchers collected samples of gas from 159 homes in different regions of California and measured to see what types of gases were being emitted into homes when stoves were off. They found that all of the samples they tested had hazardous air pollutants, like benzene, toluene, ethylbenzene and xylene (BTEX), all of which can have adverse health effects in humans with chronic exposure or acute exposure in larger amounts.

A high-resolution, wearable electrotactile rendering device that virtualizes the sense of touch
A collaborative research team co-led by City University of Hong Kong (CityU) has developed a wearable tactile rendering system, which can mimic the sensation of touch with high spatial resolution and a rapid response rate.
The team demonstrated its application potential in a braille display, adding the sense of touch in the metaverse for functions such as virtual reality shopping and gaming, and potentially facilitating the work of astronauts, deep-sea divers and others who need to wear thick gloves.
“We can hear and see our families over a long distance via phones and cameras, but we still cannot feel or hug them. We are physically isolated by space and time, especially during this long-lasting pandemic,” said Dr. Yang Zhengbao, Associate Professor in the Department of Mechanical Engineering of CityU, who co-led the study.

Artificial intelligence helps predict performance of sugarcane in the field
A Brazilian study published in Scientific Reports shows that artificial intelligence (AI) can be used to create efficient models for genomic selection of sugarcane and forage grass varieties and predict their performance in the field on the basis of their DNA.
In terms of accuracy compared with traditional breeding techniques, the proposed methodology improved predictive power by more than 50%. This is the first time a highly efficient genomic selection method based on machine learning has been proposed for polyploid plants (in which cells have more than two complete sets of chromosomes), including the grasses studied.
Machine learning is a branch of AI and computer science involving statistics and optimization, with countless applications. Its main goal is to create algorithms that automatically extract patterns from datasets. It can be used to predict the performance of a plant, including whether it will be resistant to or tolerant of biotic stresses such as pests and diseases caused by insects, nematodes, fungi or bacteria, and or abiotic stresses such as cold, drought, salinity or insufficient soil nutrients.
Scientists find a new contributor to Alzheimer’s disease
Alzheimer’s disease is a brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks. In most people with the disease — those with the late-onset type symptoms first appear in their mid-60s. In a study from Brigham and Women’s Hospital, scientists found a new contributor to Alzheimer’s disease.
